Purpose of the Test

The AFB Smear/ZN Stain is used to diagnose TB or other related bacterial infections, such as pneumonia. The test is also used to monitor the effectiveness of treatment for these infections.

When this test is required

The test may be requested when a healthcare provider suspects that a person may have TB or other related bacterial infections. This suspicion may be based on clinical signs such as a persistent cough, fever, night sweats, and weight loss. The test may also be requested as part of a routine screening program to detect TB or other bacterial infections in high-risk populations.

What the Test Detects

The Aspiration Fluid AFB Smear/ZN Stain test is used to detect the presence of acid-fast bacilli (AFB) in a sample of fluid that has been removed from a body cavity through aspiration. AFB are bacteria that have a waxy cell wall that makes them difficult to stain with standard laboratory techniques. The Ziehl-Neelsen stain is used to make AFB visible under the microscope.

Preparation for the Test

The sample required for an AFB Smear/ZN Stain is usually fluid that has been aspirated from a body cavity, such as the lungs or pleural space. Other samples that may be tested include cerebrospinal fluid and peritoneal fluid.

Additional Notes

If a person tests positive for TB or other related bacterial infections, they may need to be treated with antibiotics. It is important to follow the treatment plan prescribed by the healthcare provider to prevent the spread of infection to others. The test may need to be repeated several times to monitor the effectiveness of treatment. It is important to work closely with the healthcare provider to manage and control these types of infections.
